I took out the rune that I had prepared for 3 days. With my knowledge from my past lives, making any runes is possible for me; if I want, I can even make a new one right here.
I threw the rune on my hands to the ground, and immediately after, a massive circle formed beneath me.
This rune is called the 'No mana room'; anyone who is inside this rune will be exempt from using the mana or any other form of energy.
The time for that varies on the quality of the rune; this is a low-class one; I did not have enough materials to prepare the best one.
But even this is fine to keep that bastard here for 10 minutes.
I could have used my domain too, but it will be noticed by the Legendary Sorcerers present in the castle; if they found out, it will be hard for me to do my work.
There is also the possibility of them sensing the use of this rune, but I am prepared for that.
"Come out, dragon," I said, ordering my first and only undead being to come out.
